Challenges in Hyperon Decays
Darwin Chang
We give an personal overview of some of the unsolved problems related to hyperon decays. We cover nonleptonic decays, radiative decays and magnetic moments. Some of the theoretical…
On A New Class of Models for Soft CP Violation
David Bowser-Chao, Darwin Chang, Wai-Yee Keung
We elaborate on a new class of models proposed recently by us and compare with another class proposed by Georgi and Glashow(GG). The models can be roughly classified as the righted…
How to Observe the Interference Effects of Top quark polarizations at Tevatron
Darwin Chang
Using a simple analytic expression for with the interference…
The Effect of Top Quark Polarization at Hadronic Colliders
Darwin Chang, Shih-Chang Lee, Paul Turcotte
We derive a simple analytic expression for q \bar{q}, g g -> t \bar{t} -> b W^+ \bar{b} W^- -> b \bar{l} ν_l \bar{b} l' \bar{ν_{l'}} for on shell intermediate states with the inter…
Loop-Induced Majoronic Decay of Neutrinos:
Darwin Chang, Jiang Liu, Palash B. Pal
In models where the suppression of the tree level couplings of fermions with Goldstone bosons is not protected by symmetry, the loop-induced couplings can in general dominate over…
CP violation in top pair production at an e^+e^- collider
Darwin Chang, Wai-Yee Keung, Ivan Phillips
We investigate a possible CP violating effect in annihilation into top quark pairs. As an illustrative example, we assume the source of the CP nonconservation is…
